(54) CONVEYOR LINE FOR THE PRODUCTION OF REINFORCED CONCRETE PRODUCTS

The invention relates to devices for the manufacture of reinforced concrete products, in particular exterior wall panels of residential and industrial buildings.

A known conveyor belt for the manufacture of reinforced concrete products includes a two-branch molding line, in which one branch is located in the demolition posts, and the second is all other technological posts required, and a two-branch tunnel heat treatment chamber. The longitudinal axes of the car forms are perpendicular to the axis of the conveyor, and the paver rail guides are installed above the level of the process equipment 1J.

In a known line, the heat treatment chamber is flush with the molding line and occupies a significant production area. The absence of the pre-chamber and the remoteness of the posts are refined from the village. Preparing molds on this line makes it difficult to pre-strip, remove mold elements and transfer them to the mold preparation posts.

The closest to the technical essence of the present invention is a technological line for the manufacture of construction products, containing parallel molding molding conveyor branches with a heat chamber at one end, transfer devices connecting them at the ends into a single closed process flow, trolley forms, lifts reducers installed between the heat chamber and the forming conveyor branches, technological posts with equipment dedicated to one side of the conveyor belt for stacking and compaction tim mix concrete, pre demolding and finishing, on the other - for cleansing, lubricant forms a charging valve,

20 laying finishing materials, final finishing of the surface of products, their configuration, stripping and removal from the conveyor, and lifting mechanism C2.

In the described line is also missing prechamber. The location of the hoisting-and-transport mechanism over the molding posts and the absence of an intermediate stock of component parts, including form-building equipment.

makes it difficult to pre-strip and transfer mold components from finishing posts to mold preparation posts and reduces productivity.

The purpose of the invention is to improve product quality and productivity.

This goal is achieved by the fact that a conveyor line for the manufacture of concrete products, containing two parallel molding conveyor lines with a heat chamber at one end, transfer devices that connect them at the ends into a single closed process flow, trolley forms, reduction arms installed between the ends heat chamber and molding conveyor branches, technological stations with equipment designed on one branch of the conveyor for laying and compacting concrete mixtures, preliminary stripping and finishing, and on the other - for cleaning, lubricating molds, charging with fittings, laying finishing materials, finishing the surface of products, their configuration, stripping and removal from the conveyor, and the lifting and transport mechanism equipped with a preliminary heat treatment chamber located between the equipment for laying and compacting concrete mixes and pre-stripping of products, and the lifting-transport mechanism is mounted on the prechamber chamber with the possibility of movement along its longitudinal axis.

The drawing shows the proposed line.

The line contains two molding branches with molds 1, a puttying machine 2, a mechanism 3 for opening the sides, a tilter 4, a mechanism 5 for closing the sides, a bridge 6 for the molding equipment, a mortar 7 for the lower layer, a transfer device 8 used, for example, for installing rebar frames 9 using a crane 10, pushers 11, vibrating plate 12, concrete paver 13, supplied with concrete mix from the gallery of concrete mixing unit 14, mortar 15 of the upper layer, warehouse of component elements 16, located on the prechamber 17, On one of the walls of which a guide 18 is rigidly fixed, on which a lifting-transport mechanism 19 is mounted, lift-reducing devices 20 connecting the molding branches to the heat treatment chamber 21, which is equipped with a transfer device consisting of a traction device 22, a drive 23 located in an isolated QT high temperature compartment 24, and located in the area

heat treatment carts 25, a. also equipment 26 for laying and compacting concrete mixtures and 27 for pre-demoulding products. The process of manufacturing products on

The proposed line is as follows.

On exiting the chamber 21, the form 1 enters a post equipped with a putty machine 2 where the putty of the upper surface is made.

products. With the help of a lifting and transport mechanism 19, column blocks 16 are installed, if necessary, using

5 of the corresponding mechanism 3, the beads of the form 1 are opened, they are turned over with the help of a tilter 4 and the product is removed from the conveyor. Form 1 is cleaned, lubricated, with the help of a lift of the transport mechanism 19 of the mouth. pores and liners 16 are poured in. If necessary, a finishing material is laid (plate, etc.), decorative concrete or mortar is laid using the stacker 7 of the stacker 7.

On the transfer device 8, a reinforcing cage 9 is installed in the form 1 with the help of a valve (a crane 10. The posts of both branches can also be used for the installation of the reinforcement).

adjacent to the transfer device 8.:

At the end of the assembly and assembly of the form 1, the concrete paver 13 is placed into it and, for example, by vibrating plate 12, the concrete mixture coming from the gallery of the concrete mixing unit 14 is compacted. Then, using a concrete paver 15, it is laid

0 layer of the solution, rubbed the top surface and the product enters the prechamber 17. After exiting the lift-and-transport mechanism 19, extractors 16 are deposited from the freshly formed LIA LIA, depositors 16, which are stored on the prechamber 17, where they are cleaned, lubricated and re-used.

Forms with the product using, for example, elevators-reducers 20, are fed into chamber 21, from there to the molding line again. Then the cycle repeats.
